  • Automatic detection system for combination burnisher, polisher, and scrubber
    Patent number: 11969127
    Abstract: Multiple floor treatment operations, such as burnishing, polishing and scrubbing, may be performed using a single floor treatment machine having a motor, the speed of which is governed by a controller that responds to sensor signals indicative of the type of floor treatments pad or pads operatively coupled to the motor.

  • Methods for making and using SCR catalyst on-board diagnostic limit parts
    Patent number: 11661880
    Abstract: A method of manufacturing an on-board diagnostic (OBD) limit part and a method of testing to evaluate an OBD system. The method of manufacturing the OBD limit part includes introducing a contaminant to a selective catalytic reduction (SCR) catalyst and contacting the contaminant with the SCR catalyst for a selected period of time. The method of manufacturing utilizes a vessel, the contaminant, and the SCR catalyst. The OBD limit part is a combination of the contaminant and the SCR catalyst within the vessel. The method of testing to evaluate the OBD system includes collecting data related to an exhaust gas before and after the exhaust gas is exposed to the OBD limit part, collecting an indication provided by the OBD system, and comparing the data related to the exhaust gas and the indication provided by the OBD system. The method of testing to evaluate the OBD system utilizes a system that includes an exhaust gas source, a first and a second fluid path, the OBD limit part, and the OBD system.
